In a survey 1000 adults in a certain country were asked how many hours they worked in the previous week Based on the results a 95 confidence interval for mean number of hours worked was lower bound 37 2 and upper bound 38 9 Which of the following represents a reasonable interpretation of the result For those that are not reasonable explain the flaw Complete parts a through d below a There is a 95 chance the mean number of hours worked by adults in this country in the previous week was between 37 2 hours and 38 9 hours OA Flawed This interpretation makes an implication about individuals rather than the mean B Flawed This interpretation implies that the population mean varies rather than the interval OC Correct This interpretation is reasonable OD Flawed This interpretation implies that the mean is only for last week b We are 95 confident that the mean number of hours worked by adults in this country in the previous week was between 37 2 hours and 38 9 hours OA Flawed This interpretation makes an implication about individuals rather than the mean OB Flawed This interpretation does not make it clear that the 95 is the probability that the mean is within the interval OC Flawed This interpretation implies that the population mean varies rather than the interval D Correct This interpretation is reasonable c 95 of adults in this country worked between 37 2 hours and 38 9 hours last week O A Correct This interpretation is reasonable OB Flawed This interpretation does not make it clear that the 95 is the probability that the mean is within the interval C Flawed This interpretation makes an implication about individuals rather than the mean OD Flawed This interpretation implies that the mean is only for last week
